RAIL WITH TRIPLE HEAD.

No. 871,563. Specification oi To all whom it may concern: Berit knownthat I, ANDRE VIRGILE PAUL MA IE BERTHIER, pasha, a citizen of theFrench Republic, and resident of Constantinople, Turkey, have invented acertain new and useful Rail with Triple Head, of which the following isa specification.

This invention relates to rails for railway tracks and its object is toprovide a rail havingya. triple head so that it may be turned over twiceatits place so as to allow successively the use of the three heads forrolling purposes. Gonsequently this rail must give strictly speaking,the triple use of a rail with a single head.

The section of the rail presents three head-s and three webs connectedin their center, the three heads as well as the hollows separating thembeing strictly symmetrical; the form of the hollows is such that therolling operation may be carried out without difficulty.

The rail with three heads which forms the object of this invention maybe secured to metallic or wooden sleepers.

. In the accompanying drawings: Figures 1 and 2 show a cross section anda plan view of a rail portion secured to a wooden sleeper. Figs. 3 and 4show in a similar manner a rail portion secured to a metallic sleeper.Fig. 5 is a cross section of a fish-plate connection.

1Rail secured to a wooden sleeper. The rail 1 Figs. 1 and 2, reposesexclusively on a ground plate 2 made of metal, wood or any othersuitable material; this ground late exactly fits into the hollow of therai a plied on it, it receives and transmits to t e sleeper 3 all comression strain.

In order to re uce the height of the rail over the sleeper the two lowerheads 4, 5 project into two grooves arranged in the slee er;" thedimensions of these grooves are slig tly larger than those oi the headswhich are thus prevented from coming into contact with the sleeper; theg.ooves have a certain inclination towards the outside in order toinsure the escape of the water. The grooves are not indispensable andthe rail may simply be placed on the sleeper Without however touchingit; the height of the ground plate has been chosen in accordance as wellas that of the attaching means.

The above described arrangements do Letters Patent.

they are protected against the mutilations and deformations which occurwith double headed rails; furthermore the lower heads being free, thestrain is supported by their two webs without it being possible thatdeformations occur in the transverse direction.

Fastening the rail on the sleeper is efl'ected as follows: The groundplate is first placed on the sleeper and according to the attachingmeans used for the rail, it carries either a stay bolt, screwed orriveted in its center or projections arranged under the ground plateduring manufacture; the ground plate may also be fixed by means of awood screw with i a countersunk head, a screw or a simple nail driven inthe sleeper and whereupon. the ground plate is fixed a passage holehaving been arranged in it to this ei'l'ect. One only of theseaccessories is necessary in the case where the sleeper is united withthe rail by means of two clips. -When the rail is fixed at least bymeans of one wood screw crossing one of the lower webs and the groundplate, the latter is at the same time kept in place. The rail is securedto the wood sleeper either by a wood screw 6 and a clip 7, or by twowood screws or by two clips.

2. Rail secured to metallic sleeper.-One may for instance use sleepersmade of rolled and stamped soft steel (Figs. 3 and 4); a projection 8replaces the ground plate 2 used with the rail on wood sleeper anddepressions 9, allowing of the lower heads being lodged, are provided inthe sleeper by stamping. The

ollows 9 may be dispensed with; in this case the projection bein used asground plate as well as the attaching means are in this case heightenedso as to insure the position of the rail without the lower heads intocontact with the sleeper.

The rail is secured to the sleeper either by means of two clips 7 or byonly one clip and a belt, or by two bolts: the latter ordinarily crossthe lower webs and the ground plate like the wood screw 6, Fi 1.

It is advisable to provide with a catch the bolts intended to keep theclips or to traverse the webs; when the boltis introduced from below thecatch traverses a. suitable mortised roove provided in the sleeper forallowing fire catch to pass; then the bolt is caused to rotate abouthalf a revolution and in this position the catch prevents any tendencyof the bolt to fall under the slee er; the

away with any contact between the lower rail heads and the metallicpieces, whereby clip carries beneath a hollow whic covers and inclosesthe catch and when the nut is in place, the bolt is prevented fromrotating which facilitates the tightening operation.

When the bolts connect the rail to the sleeper without the help ofclips, a washer is interposed under the nut; it is provided with amortised hollow intended to receive the catch of the bolt.

Whether rails are used on wooden sleepers or on metallic sleepers theconnection between the rail ends is effected by means of fish-plates 10having the section shown in Fig. 5. These fish-plates are secured inplace by bolts having rectangular heads 11; this form of head beingnecessary by reason of the necessity of leaving between it and the upperpart of the rail a suflicient space for the passage of the Wheelflanges. The base of the bolt is preferably square.

It is also possible to use three fish-plates kept in place by sixalternating bolts and in this case the rail may be rotated Withoutseparating all the rails.

Having now fully described my said invention, what I claim and desire tosecure by Letters Patent is:

1. The combination with the three headed rail of a sleeper intended tosupport the rail of a ground piece constituting the intermediary betweenthe rail and the sleeper and having such a form as to fit the outlinesof the hollow of the rail which bears upon the ground plate, of twogrooves provided in the sleeper and adapted to receive the two lowerheads of the rail, the ground plate preventing the contact between thesetwo heads and the sleeper, substantially as and for the purpose setforth.

2. The combination with the three headed rail and a sleeper, of a groundplate and grooves provided in the sleeper, of attaching means betweenthe ground plate and the sleeper.

3. The combination with the three headed rail, the sleeper provided withgrooves, the ground late of attaching means between the rail and thesleeper, these means traversing one of the lower webs of the rail. Intestimony whereof I have hereunto set my hand in presence of twoWitnesses.
